Power and discourse in the politics of evidence in sport for development

The field of sport for development (SFD) has been criticised for the way that evidence has been produced and used to account for and demonstrate the perceived success of SFD programmes. Much of this critique has highlighted shortcomings in approaches to monitoring and evaluation (M&E), which underpins a perceived weak evidence base concerning what works, why and within which contexts (Coalter, 2007, Coalter and Taylor, 2010, Pawson and Tilley, 1997). Conceptually a lack of evidence discourse (Nicholls et al., 2010) has emerged. This paper explores and analyses the power dynamics that shape this discourse and argues that an understanding of the dominant neoliberal context within which SFD is located is critical. While offering a Foucauldian framework, the power, knowledge and discourse related to political actors in SFD processes are examined. This paper addresses two key questions: what is power and who is it for? Whose interests are served in the interpretation, generation and reporting of evidence? The paper concludes that the role of the sport development practitioner (SDP) is underprivileged and to enable the field of sport for development (SFD) to move forward, the very people who implement the programmes need to be better understood. Furthermore it is argued that a deeper understanding and interpretation of the terrain of the sport development practitioner (SDP) within UK and international shores are a necessity if a more open and transparent knowledge transfer process, surrounding evidence, is to be entered into.     

最大摄氧量间接测定方法PWC170法与两步台阶实验法比较研究

采用文献资料法、对比法和数据统计法,对最大摄氧量及其间接测定方法进行了研究分析,初步总结出最大摄氧量受遗传、性别、年龄、环境、营养饮食状况、生活习惯和训练等因素的影响.运动时对心肺功能的测定是科学训练的一个重要方面.而评价心肺功能的最佳指标是最大摄氧量,最大摄氧量是反映有氧工作能力的有效指标之一.通过对最大摄氧量间接测定方法PWC170法与两步台阶实验法比较研究,有利于从测试的精确度、测试的简易性、测试的效率、测试费用及训练评价效果方面提供更好的理论依据.

我校护基操作教学中双核动力式学习的探究

我校护理教研组为了探讨双核动力式学习模式在基础护理操作教学中应用效果,把护理专业的298名学生随机分为双核动力式学习组和传统式教学组,分别采取相应的教学模式,通过阶段性护理理论、各项护理操作考核和学期结束时问卷调查,分别作为教学效果评价的指标进行评估比较,结果表明,双核动力式学习法在护理操作教学中的教学效果明显优于传统教学法,值得进一步的研究和推广。     

行政与司法角力下的特殊权力关系理论

权力的本性是毫无理性的自我膨胀和扩张,权力最难忍受的是其他权力对其的倾轧和剥夺,法治国下设计权力制衡的理论原点也就在于利用这一本性以“恶”制“恶”,经过权力之间的博弈,最终将权力限制在各自应在的范围之内,达到一种政治权力的平衡状态,保护政治共同体下公民的权利的终极目的在这一过程中,自然地发生和实现。特殊权力关系理论的一个核心问题是司法救济能否进入行政权保守的领域。     

Influence Tactics in the Classroom and Their Relationship to Student Satisfaction*

We argue that an instructor's use of influence tactics can be classified as soft, rational, and strong in nature and that the use of these tactics will have a differential impact on student satisfaction. We find support for the existence of the three categories of influence. We find that student satisfaction is positively influenced by the use of soft and rational tactics, but is uninfluenced by the use of strong tactics.     

报告文学家的热血和力量--我的创作体会

报告文学家是时代的弄潮儿，社会的观察者，舆论监督的一员，应当响亮地喊出“干预生活”的口号，弘扬真善美，鞭挞假丑恶，为社会匡正除弊。这就是报告文学家的热血刚肠和道德力量。     

Influence of technique on upper body force and power production during medicine ball throws

ABSTRACT

This project examined the interrelationships between power production and upper body kinematics during a series of medicine ball push-press (MBP-P) throws. Twenty-five regular weight trainers (body mass = 86 ± 10 kg) performed a series of ballistic vertical MBP-P throws at loads representing 5% and 10% of their assessed 5RM bench press. Throws were performed lying supine on a force platform (1 kHz) with upper body kinematics assessed using standard infra-red motion capture techniques (0.5 kHz). Gross measures of performance and power production such as peak vertical ball velocity (Vel_peak), peak force (F_peak) and power (P_peak) were recorded during the propulsive phase of the movement. Comparative analyses indicated that despite significant reductions in Vel_peak from the 5% to 10% loads (P < 0.001), F_peak remained largely unchanged (P = 0.167). Analysis of inter-trial variability showed that the gross measures of performance and power were relatively stable (Coefficient of Variation [CV%] <13%), while most upper limb segmental kinematics varied considerably between trials (CV% up to 70%). This project highlights the complexity of the relationships between power production and upper body kinematics during light load ballistic MBP-P throwing. Additionally, it shows how trained athletes can achieve similar outcomes during ballistic movements using a variety of movement strategies.
